Ios 地牢生成算法正在生成不需要的结果
我使用SpriteKit为iOS编写了一个用Swift生成地下城的算法。该代码的功能与预期一样，可以生成具有四条边的正多边形。但当我切换到8路邻接组时，生成器开始出错 下面是生成地牢的代码，其中包含用于表示房间和走廊的单个瓷砖的一些屏幕截图Ios 地牢生成算法正在生成不需要的结果,ios,swift,sprite-kit,sktilemapnode,Ios,Swift,Sprite Kit,Sktilemapnode,我使用SpriteKit为iOS编写了一个用Swift生成地下城的算法。该代码的功能与预期一样，可以生成具有四条边的正多边形。但当我切换到8路邻接组时，生成器开始出错 下面是生成地牢的代码，其中包含用于表示房间和走廊的单个瓷砖的一些屏幕截图 import Foundation import SpriteKit private let mapWidth = 100 private let mapHeight = 100 class Room { // these values hol
